   Back Pressure Robs your Vehicle of Power and Economy. Reduced Back Pressure will cause immediate Gains in both Power and Economy. If you modify your engine, for every 8-10% in Power Increase you will gain 30% more Back Pressure which virtually Chokes the Motor. So any Modification done to the Motor makes a Free Flowing Exhaust System Mandatory.

   There are three (3) Basic Reduction of noise control: Restriction, Absorption and Reflection. Restriction is best for reduction of noise, but is the worst for Power and Economy (as High as 16lbs of Back Pressure). Absorption is effective when you pack materials such as Fiberglass inside the Muffler, but this is usually quite loud. Reflection which is the most effective for Power Increase is done with baffles and reflector plates with nothing to burn out. MAC Flow Path™ Mufflers use Reflection for maximum flow while still maintaining noise control.
